Promoting Excellence in Interdisciplinary
Research and Education in Computing
UMIACS has established several long-term partnerships, including:
• The National Partnership for Advanced Computational Infrastructure(NPACI) led by the San Diego Supercomputer Center and supported by theNSF. UMIACS faculty are participating in four thrust areas: ProgrammingTools and Environments, Data Intensive Computing, Earth Systems Science,and Resources.
• The Laboratory for Telecommunications Sciences (LTS), a major collaborativecenter between the Department of Defense, industry, and academia. Universityof Maryland work focuses on a broad research program dealing withfundamental and applied research in the design, performance, and managementof distributed heterogeneous networks.
• The Army Research Lab Collaborative Technology Alliances involvingresearch in advanced sensors, sensor fusion, image analysis, artificial intelligence,and computer vision algorithms for the navigation of vehicles over ruggedterrain.

Downloading Landsat Enhanced Thematic Mapper Data: The GLCF provides dynamic access to over 5,000 Landsat
satellite images through an internet map server. The map server allows querying by geospatial events such as
earthquakes or carbon emission. The image shown is a preview of an 185km x 175km satellite acquisition.

UMIACS Centers enable faculty to workon common interdisciplinary themes thatare pursued through several majorsponsored research programs. One or morelaboratories are typically affiliated with eachCenter.
Center for Automation Research
The Center for Automation Research(CfAR) conducts research on computervision, graphics, image and videounderstanding, and robotics through threeconstituent laboratories.

Computer Vision Laboratory
The Computer Vision Laboratory wasestablished in 1964 and is widely regardedas one of the top computer vision labs inthe world. Research areas includecomputational theories of visual perception,virtual and augmented reality, navigationand object recognition, surveillance ofhuman activities, image and videodatabases, spatial data structures, andgeometric foundations of image analysis.

Tracking of people in groups:
Input image (upper left);
assignment of foreground
pixels to people (upper right);
segmentation of each person
into parts (lower left); and
occlusion model showing
relative positions (lower
right).
Moving this pattern produces different apparent motion in the inset
and the background. The reason is the inherent difficulty of any
vision system to deal with statistical bias. See, Fermuller et al, Vision
Research, 40, 2000, 77-96.
